UI: move all items in menu to the right as if there was an icon
If there's no icon, just fraw empty space. This makes popup menus
with no icons at all looks similar to popup menus with icons and also
makes item labels more readable. In general, looks much better and
fits better into modern desktops (GNOME & Windows behave the same).

like a normal editField, but does filename-completion on the last word of
the contents, when TAB is pressed.
Filename completion ignores regular files if directoriesOnly is true,
and ignores directories, if filesOnly is true. Both default to false.
